package BRepFeat
- ---Purpose: BRepFeat is necessary for the
- -- creation and manipulation of both form and mechanical features in a
- -- Boundary Representation framework. Form features can be depressions or
- -- protrusions and include the following types:
- -- - Cylinder
- -- - Draft Prism
- -- - Prism
- -- - Revolved feature
- -- - Pipe
- -- Depending on whether you wish to make a depression or a protrusion,
- -- you can choose your operation type between the following:
- -- - removing matter (a Boolean cut: Fuse setting 0)
- -- - adding matter (Boolean fusion: Fuse setting 1)
- -- The semantics of form feature creation is based on the
- -- construction of shapes:
- -- - for a certain length in a certain direction
- -- - up to a limiting face
- -- - from a limiting face at a height
- -- - above and/or below a plane
- -- The shape defining the construction of a feature can be either a
- -- supporting edge or a concerned area of a face.
- -- In case of supporting edge, this contour can be attached to a face
- -- of the basis shape by binding. When the contour is bound to this face,
- -- the information that the contour will slide on the face becomes
- -- available to the relevant class methods. In case of the concerned
- -- area of a face, you could, for example, cut it out and move it at
- -- a different height, which will define the limiting face of a
- -- protrusion or depression. Topological definition with local
- -- operations of this sort makes calculations simpler and faster
- -- than a global operation. The latter would entail a second phase of
- -- removing unwanted matter to get the same result.
- -- Mechanical features include ribs - protrusions - and grooves (or
- -- slots) - depressions along planar (linear) surfaces or revolution surfaces.
- -- The semantics of mechanical features is based on giving
- -- thickness to a contour. This thickness can either be unilateral
- -- - on one side of the contour - or bilateral - on both sides. As in
- -- the semantics of form features, the thickness is defined by
- -- construction of shapes in specific contexts.
- -- However, in case of mechanical features, development contexts
- -- differ. Here they include extrusion:
- -- - to a limiting face of the basis shape
- -- - to or from a limiting plane
- -- - to a height.
